Application filed March 9, 1911.. Serial No. 613,420.

To all wzom t may concern Be. it known that I, Orro SCHMIDT, a. subjectot the KingI of Prussia, of 4 Kurzestrasse, Haspe, in lVestphalia, inthe Kingdom of Prussia, Empire ot' Germany, master coppersmith, haveinvented certain new and useful Improvements in Apparatus torlnexplosively Storing and l)rawinj Oil' Igni'terous Liquids; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichitappertains to make and use the same.

My present invention relates to anapparatus, or plant, for inexplosivelystoring and drawing-ott' ignit'erous liquids, which is operated by meansof water-1n'essure in such a manner that the bulk. of the displacedivniferous liquid, such as benzin, coal-oil or t'iellike, is replaced bythe watel as usual, and which plant is provided with means executing`their several functions automatically as soon as the air surrounding theapparatus reaches a certain degree ol. temperature, or `a tire breaksout in its neighborhood. In the first. instance the igniterous liquid inthe storage-tank will be cooled through its bodily contact with thewater, but in the second instance, in addition to this, the storage-tankwill be energetically cooled-ott' from withoutI by sprinklingmeanssimilar to those employed tor stages and other rooms more or less likelyto take tire. The possibility of an explosion is tur ther minimized bythe tact, that the water employed for displacing the ignit'erous liq uidenters the storage-tank through a standpipe which surrounds thedischarge-pipe ot the igniferons liquid so completely, that the latteris kept cool at all times. Besides this, means are provided, capable ofleading-ofi' any volati'le `gases and vapors which may collect andattain a pressure which, if not duly reduced or relieved, might provedanzgjerous to the apparatus or the whole plant.. ln this manner it ismade possible to lfeep the igniferous liquid even in presence of a tireso cool as to prevent its explosion and thus most effectively preventthe loss of lite and property.

In the accomlmuying' drawinf's:-Figure 1 is a vertical sectional view otmy invention, Fig. 2 is an elevation of the means elnployed for usuallyadniittin;Y the water for ed arm displacing the igniferous liquid, orcoollng the latter and the storage-tank m case the combined water-outletand dischargepipe. Y V

Upon the top of the storage-tank l an `mfertlow-ehamber 2 is arranged,which in turn surn'iounted by a casting 3. The latter supports astand-pipe d carried upward through the roof of the building, and a pipe5 which extends downward and ends within a short distance above thebottom ot' the overtlow-chamber 2. lVithin said casting` 3, stand-pipe tand pipe 5 the diseharge-colunm is arranged, which passes upward abovethe highest tap 7 and downward through the bottom of the overflowchamberinto the storage-tank 1, whereas itis enlarged within the casting' 3 toform a double-seated valve-casing' 8 to which the .feed-pipe 9connected.' Through the latter the igniterous liquid is forced from thebarrel l() by means ot the force-'pump 11 in the usual manner.' lVi thinthe easing S the valvescats l2 and 13 are formed, the former above andthe latter below the lamide-sleeve let. In thisI sleeve a guide-rod 15is guided which ax-ries the valves 1G and 17 arranged Vin such a`manuel', that when the one is seated the other is opened, and viceversa;

or both valvesare open at the same time, as shown n1 the drawing. The`guide-rod l5 also passes through the flame-extinguisher 1S arranged atthe lower end ot the disch-arg0-column G and is further guided in abracket 19 secured to the bottom of the storage-tank 1. To keep thevalves 16 and 17 in their normal position, said valverod is balanced bymeans of t-he weighted lever 2O always duly returned to its normalposition by the aid of its weight- 20 acting as a pendulum. r1`hevalve-rod l5 pets 21 and between which a tloat; or swinnner 23 ot suchspecific gravity is arranged, that itwill not be carried upward. by theigniterous liquid, but will always vremain in Contact vith tho body ofwater which carries and discharges said liquid is further provided withtap- 30 and. ma

of 09mm ngef which @amies at its en hi; i? uffi is nsened 'mth 63h@ 'lth@ whQe by means c x it lover @mi to che fiom' 3:3 by the 10 hook 5100s. the luie., The tue m' mais of mail@ mi wfg ch .is easily stand- )i)e at and V artly downward throiieh t l i, i

the pipe 55 to the perforated coiled pipe or sprinkler G ar ang'cd ontop olI the storagetank l. That part of the water which pas es throughthe valve 5l into .the stand-pipe 4 flows along with the water from thebypasspipe 3S to the tank to cool the contents.

thereof, whereas the part ot the water which flows through the pipeflows into the sprinkler '56. from which it runs in small streamlets allover the top and sides ot' the tank l to keep the latter and inconsequence thereof its contentsv cool. To n'iake the automaticallyoperating` water-suppliers arranged upon each floor act 4independentlyof each other, their pipes are led to a head common to both, with whichthe sprinkler 56 is connected. lty will thus be seen that the plantprotects itselt autoinatically against the. dangers entailed by a tire.,since ity not only compels the water to toi-m a cooling \\ater-mantlearound the discharge-column ot the liquid and around the shell of thestorage-tank, hut also brings it. into bodily Contact witlrthe liquiditself notwithstanding the fact, that the cock tl, usually admitting thewater for displacing;- the liquid, closed.v By means ot thisl inventionit is thus made possible to obtain the greatest protection against thedestructive consequences ot an explosion ot the igniterous liquid, sincethe latter will always he. kept oolow the dangerous temperature so lon;aS The autonnitically operating` water-suppliers arc not destroyed.
